This is a large blade at almost 12'long. I like making big knife blades but I donít get too much, it seems most like the smaller pieces. But once and a while I make one on speculation to make myself happy. The blade is made out of 1095 and nickel 200. The two outer most bars are a fairly tight clockwise twist and the center bar is a slower twist counterclockwise and the two inner bars are a straight laminate.
